摘      要：We simulate pedestrian counterflow by adopting an optimal path-choice strategy and a recently observed speed-density *** the whole system is symmetric,the simulation demonstrates the segregation and formation of many walking lanes for two groups of *** symmetry breaking is most likely triggered by a small numerical viscosity ornoise,and the segregation is associated with the minimization of travel *** underlying physics can be compared with theoptimal self-organizationmechanism in Helbing s social force model,by which driven entities in an open system tend to minimize their interaction to enable them to reach some ordering state.
